scRUBBINc-MACHINE.

I i Specification of Letters Patent.,

To .all whom' it may concern."

' Beit known that I, CHARLES' a citizen of the United States, and'resident of Iron Ridge, in the Acounty of Dodge and State of Wls'consin, have invented certain newganduseful Improvements in Scrubbing- Machines; andI do hereby `declare that the following is afull, clear, and exact description thereof.

. The object of my invention is t provide a simple, economical and effective scrubbingmachine, its .construction and arrangement being such that by means of a series of rotatory fountain brushes and mop, all of which are hung 1n a suitable truck, an operator may lwith.slight-exertion, readily sweep, scour,

andwipe, all'arge area of-floo'r space ma comparatively. short space of ti1ne, and at a singleoperation. l A

Said-`nvention therefore comprises various details of construction-and".combination of partsgas. set forth hereinafterfwith reference tofthe accompanying drawings land subse-A quently claimed.v

In the A drawings: vFig'gure 1i represents a .side elevation of va machine embodying the features oftmy'invention; Fig. 2 a sectional i elevation 'of the same looking from the oppovsite side., withparts broken away, the section being-.indicated by line 2-2 of Fig'. 3, and

' Fig. 3,1aplan viewof the machine with parts removed, other` portions in section to better 4illustrate details of construction.` p 'l-'Referrlngby letter to the drawings, A indi cates a-truck-frame provided with lrubberfaced forward traction-wheels B, B', and' rear casters o, the. side-bars of the frame being extended above traction-wheels and connected by a cross-barb, to which -bar is secured a Water-`supply tank ACof any suitable caistruction.'y Pivoted to the sidebar extensions-.of the truck-frame is a bail c to whichis secured ahandle D, a projection d of thebail being'dir'ectly over. a cross-bar e ofa 'supplementary frame E to lbe hereinafter more fully described. The traction-wheels .B, 'B"are fast to a hollow-shaft D7, which shaft 'has'its bearingin bosses of theitruckf frameandfintermediate o`f the side-bars ofl said frame. lheshaft is fitted with and has .the hollow shaft.. communicate. The/ supplementary frame E is located to the rear of the'traction-wheels and within the side-bars of the truck-frame, to which itis connected Patented May 4, 1909.

by apertured'ears g lprojecting from said H. HE'NNING,.'

frameE and engaging posts h that extend upward from ears of the truck-frame sidebars, there' being `coil-springs 'i surrounding the )osts intermediateof the ears.. The ends of t 1e posts 7L are threaded for the recelption of adjusting nuts j, by means of'whici the/ supplementary frainemay be vertically adjusted'in op osition to the springs, which springs tendp to ylift said supplementary frame. The supplementary frame E is also provided with front bearings for a cylindrical brush F, having an apertured hollow shaft G communicating with its tufts similar'to the brush previously described, and to the rear of the:brush F a spindle H is revolubly 'mounted in the frame E', this spindle being provided with a jacket of absorbent material I, preferably a sponge, forfthe purpose of wiping u and absorbing the 'water discharged from the fountain brushes, which brulshes receive their supply from the watertan v A discharge-cock J is connected to the bottom of the water-tank, one openingof which cock has a pipe lc leading Atherefro1n,its bent lower` end being fitted into an aperture of the hollow 'shaft D. A second nozzle opening in the cock is connected by a flexible tube to al pipe m, which pipe is secured to the supplementaryframeVits open end being tted into an open end of the hollow shaft G of the second brush.

by the water absorbed Vby said sponge isl `s ueezed out as it asses said wall, from w lich it drains into t e tank. i

,The water that is caught'in thereceiving tank is pumped b ack into the supply tankC, by means of a pump L secured thereto, a valve-controlled nozzle of which pump is connected by a hose toa pipe-section p that rises from the bottom of said receiving-tank,

'there being a suitable valve-controlled dis` charge-nozzleq at the topof the pump communicating with said supply-tank, whereby the Water is forced therein at each stroke of the pump-piston, which piston is actuated by a pitman 'l' in Wrist-pin connection With the traction-wheel B, as shown in' Fig. 2 ofsponge-'cylinder revolve in the opposite diiection from the travel of the machine, said rear brush traveling at Va much greater velocity than the front brush E, which brushI revolves in the direction of travel of the machine and at approximately tlie same speed as the traction-Wheels and sponge-cylinde, froinwhich Wheels the brushes and sponge receive their drive. c v

Assuming that vthe supply-tanlircontains the required water, the.. machine being.-

pushed over a surface"l to be cleaned, will cause the traction-Wheels to revolve, motion therefrom is transmitted tothe second brush, and the feed-cock of the water-supply tank being o en,. each brush will distribute Water upon -t ie floor. 'The vaction of the front brush tending to sweep and thronT the w ater backward or in'front of the seciond brush,

which brush will catch the same, owing to its reverse motion, and push the Water forward or delay its course for a time. The Water is then caught up by the sponge cylindei,which i;

"have hereunto set my hand at Milwaukee in revolves slowly in the saine direction as the first brush, and is delivered to the drainti'ough by the squeezing-contact of said sponge-cylinder against the same. water is 'thereafter pumped back into the supply-tank7 thus com leting a circulating system. Pressure of t e second brush and The sponge upon the floor may be varied by thevoperator forcing the projection d of the bail against the cross-bar e of the supplementary frame as required, rovision being had, by means of the adjusting nuts j and springs to permanently regulate said pressure.

While I have shown and described one method of gearing the several brushes and a. detailed construction of pumping apparatus, it is evident' that said gears and details may be varied within the skill of mechanics, without departing from the spirit of my invention. Y

I claim:

1. In a scrubbing-machine, the combination of a truck-frame, a Watersupply tank -cariied thereby, rear supporting casters for the truck-frame, a forward shaft mounted 1'n the frame and having traction-wheels secuied thereto, a brush carried by the shalt7 a' sup lementary frame in yielding-connection Wit i the truck-frame, an operating handle in pivotal-connection with the truck-frame and adapted to engage the supplementaiyframe to control the yield of the supplementary frame7 a brush carried by the supplementary frame, a cylinder of absorbing material rearward of the last named brush, drivingmeans in connection with the truck-shaft, said last-named brush and the cylinderof absorbing material.' and means for distribating Water'from the. supply-tank to botli brushes.

2. A scrubbing -machine comprisinf.;l a truck-frame, a supplementary brush-carrying frame in. yielding connection with the truck-frame, an o erating handle in pivotal-l connection With t ie truck-frame and adapted to engage the supplementary frame to control the yield ofthe supplementary frame. In testimony that I claim the foregoing l the county of Milwaukee and State of Visconsin in the presence of two witnesses.
